inkrementaalvarundus, often translated as incremental backup, is a data backup strategy that saves only the data that has changed since the last backup operation. This approach contrasts with full backups, which copy all selected data every time, and differential backups, which copy all changes since the last *full* backup. The primary advantage of incremental backups is their speed and reduced storage requirements. Since only a small portion of data is backed up each time, the backup process is significantly faster and consumes less storage space compared to full backups.

The process of incremental backup typically involves a reference point, which is usually the last successful backup of any type (full or incremental). When an incremental backup is performed, the system identifies all files that have been modified, created, or deleted since that reference point. Only these changed files are then copied to the backup destination. This efficiency makes incremental backups a popular choice for regular, frequent backups, especially in environments with large amounts of data where full backups would be time-consuming and resource-intensive.

However, the restoration process with incremental backups can be more complex. To restore data to a specific point in time, one must first restore the last full backup, followed by each subsequent incremental backup in chronological order up to the desired restore point. This sequential restoration can be slower and more prone to errors if any of the incremental backup files are corrupted or missing. Despite this, the efficiency gains during backup often outweigh the complexities of restoration for many users and organizations.
